Kaplan blade

Kaplan turbines are water turbines against which water flows in an axial direction and have an adjustable blade wheel. They were developed from the Francis turbine by Viktor Kaplan. The blade wheel is similar to a ship's propeller with adjustable impeller blades. This turbine is a reaction-type turbine in which the water pressure decreases as it passes from the inlet into the blade wheel through to the outlet. Its efficiency is between 80 and 95 percent. It is suitable for large hydraulic power stations located on calmly flowing water.

For the manufacture of a Kaplan turbine, we provide efficient metal cutting tools and complementary machining processes.
